Human Fertilization

What happens to you?

During this week your body is preparing to receive a fertilized egg. The lining of your uterus gets thicker.

What happens to the baby?

Every month, halfway through a women’s menstrual cycle (day 14 of a 28-day cycle), the body produces an egg that is released from the ovaries through the fallopian tube and eventually into the uterus. This egg will need to be fertilized—fused with a male sperm—within 12–24 hours to become pregnant. If the egg is not fertilized within that time, it will pass through the vagina along with the shedding of the lining of the uterus; this is your period. Once the egg is fertilized it begins to split over and over again until a small cluster of cells is formed. By day 4, after fertilization, there are usually over 100 cells.
